Answer 1

oblicz:

(0,8)do potegi 4:(2⅔)do potegi 4=

=(4/5)⁴ : (8/3)⁴=

= [(4/5) : 8/3)]⁴ =

= [(4/5)*(3/8)⁴ =

= ( 3/10)⁴ =

= 81/10000 =

= 0,0081 

 

 

(-6,5)³:(-0,13)³=

= [(-13/2):(-13/100) ]³ =

=[ (-13/2)*(-100/13) ]³ =

= 50³ =

= 125 000

 

(4½)³·(-⅔)³·(-2)³=

= [(9/2)*(-2/3)*(-2) ]³ =

=  6³ =

= 216

 

(2½)do potegi 4 ·0,6 do potegi 4·(-1/15)do potegi 4=

= [(5/2)*(3/5) *(-1/5)]⁴ =

=  (-3/10)⁴ =

= 81/10000 =

= 0,0081

 

0,3do potegi 4·(2⅔)do potegi 4:(-4)do potegi 4)=

= [(3/10)*(8/3):(-4) ]⁴=

= [ (4/5) *(-1/4) ]⁴ =

= (-1/5)⁴ =

= 1/625
